    Well I finally got the phone call from my local RFD to say that the Huggett shroud that he had ordered me, had (finally) arrived.

    First impressions are that it was certainly worth the wait. It's a quality piece of kit (and so it should be at that price). I was a little concerned that there is only one length of shroud available, as my existing shroud is a lot longer that the more recent 'Tactical' variations etc.

    It was a bit of a pig to get on, and I can see why AoA recommend that they fit it for you. I don't know if my Airwolf barrel is slightly different from the norm, in that it has a slightly thicker band at the breech end (which the set screws bite into), but I had a real problem trying to get the shroud over this hurdle. Eventually, prudent use of a 'persuader' managed to get the shroud properly seated. I can confirm that the longer barrel does work with the shroud, but the barrel is no longer 'fully floating' within the shroud, as it pokes it's crown through a tight-fitting O-ring and into the silencer body itself. Indeed, the cavity within the shroud appears to be redundant know.

    The shorter shroud transforms what was already a perfectly balanced rifle. It now feels more pointable, but I'm convinced that this is a purely psychological effect, as the Airwolf was absolutely spot on with the original, longer, shroud.

    It was too late in the day to try the shroud out, but dry firing indoors reveals that it is already closer to the Weihrauch 'benchmark' than Daystate's own carbon fibre silencer. I'd say to be honest, that all I can hear is the whack of the solenoid doing its thing to the Harper valve.

    I'm hoping to get down to the range tomorrow, and take some snaps. I'm particularly interested to find out if the fact that the barrel is no longer fully floating, will effect this rifles awesome accuracy.

    I have one on my mct and the barrel is still fully floating, my shroud attaches to the barrel and nothing else.
    Therefores till fully floating

    Very quiet tho

    Well I made it down to the range today, and managed to take some quick snaps.

    http://gallery.me.com/cameron.wilson#100265&view=grid&bgcolor=black&sel=0

    The arrangement
    (1&2) show how the barrel protrudes past the end of the shroud and into the silencer cavity itself (3). There appears to be an O-ring (1), much like the arrangement found inside the AR20FT shroud.

    I'd describe this as a shroud fitted to a fully floating barrel, rather than the original arrangement which is a fully floating barrel within a shroud. The important difference here is that with the Huggett, if the shroud gets a knock, so does the barrel. With Daystate's original arrangement, the barrel would remain 'unknocked' as it isn't actually attached to anything at the muzzle end. With the original arrangement you can hold the rifle in your left hand, and smack the butt of the stock with your right, and feel the harmonics of the barrel vibrating freely within the shroud. Not so with the Huggett.

    I can't quite tell if the three apertures (1) allow a back pressure to travel down the body of the shroud and out of the shroud vents (4&5). If not, the volume inside the shroud will remain untapped, rendering the shroud and its vents nothing more than rather expensive eye-candy. Either way, there is no detectable pressure generated by the shroud vents during the firing cycle.

    Likewise the silencer body vents (6) don't appear to produce a blast of air either.

    There are three flutes machined into the top of the shroud (7) in a similar style to the flute machined into the underside of a MK4s barrel shroud, and these appear to be purely decorative. They aren't like the flutes found on a high-end full-bore barrel where the increased surface area helps to cool the barrel quicker.

    The Huggett Shroud significantly reduces the overall length of the Airwolf (8&9). My full-length Airwolf is now a couple of inches shorter, and now resembles the length of the Tactical model.

    But how does it perform?
    Well, actually, that's quite hard to tell. Screwing Daystate's carbon fibre Airstream reflex silencer to original shroud, or Weihrauch's 'benchmark' High Efficiency for that matter, results in a system where the majority of the noise that you hear is actually the 'pung' of the solenoid opening the Harper Valve. There's no doubt that the Weihrauch is noticeably quieter than the Daystate, but the downside is that the Weihrauch turns the rifle into a musket. I personally found it difficult ascertain if the Huggett was quieter than the Weihrauch, but even matching the Weihrauch's legendary performance in such a compact form-factor is a major achievement.

    I then switched to shooting the 100yd targets, and after a few shots my ears started to tune-out the 'pung' of the solenoid, and I was able to hear the 'fizz' of the pellet making its way down range. I haven't heard this with any other silencer arrangement before, including the Weihrauch, so I would say that yes, on account of the Huggett revealing the 'fizz' of the pellet in flight at 50-100yds, it must be quieter than the Weihrauch. Obviously the arrangement of vents etc. (4,5&6) is actually working even although there is no apparent blast of air – they're not just there to look good!

    Accuracy
    The jury's still out with regards to accuracy. I was unable to match the group sizes that I've achieved in the past, but I strongly suspect that this has more to do with parallax error caused by the stocks low cheekpiece rather than anything else. I was able to put pellets through the same hole at 35yds, and into an ever growing single hole at 45yds. There were fliers, but again, that was most likely down to me having my jaw on the cheekpiece of the stock rather than my cheek.

    Initial summary
    The Huggett silencer is an impressive piece of kit. It's beautifully made, and it results in a truly stunning rifle. Its ability to better the Weihrauch's performance in such a compact form-factor is a major achievement, and well worth the asking price.

    I paid £140 for mine.

    But I've heard of other people paying as 'little' as £115.
